Thank you for purchasing a SANKYO Torque Limiter. These instructions contain important information on the installation and adjustment of a SANKYO Torque Limiter. Read carefully to obtain optimum performance of this product. This instruction manual should be maintained in a safe place and made readily available for future reference.

1. Description of TAD series

Sankyo's torque limiters are reliable overload protection devices equipped a torque shutting down mechanism. It is therefore that Sankyo's torque limiter features highly accurate shutting torque and easy-to-adjust torque setting.

Sankyo developed TAD series as an overload protection device particularly for output shaft of Sankyo's TAD series, an indexing drive equipped a reducer and a motor in one house. Before using the torque limiter, please refer to the table of specifications shown at catalog to make sure that actual usage is in allowance value.

^CAUTION

Tightening more than Ym, maximum tightening length might be a cause of improper functioning of the Torque Limiter.

[Relation between tripping torque and spring deflection]

When allowable torque is adjusted, please refer these graphs to find the amount of spring deflection. Number of rotation for the pressure nut could be roughly estimated by dividing the amount of the spring deflection by P, thread pitch.
